Acer vx5-591G I removed Mosfet and it works without it?! could it cause problem?

Hello everybody,

I'm learning alone at home (with you) of course.

I have an Acer VX5-591G laptop that was given to me as scrap where I was training and diagnosing.

The Laptop turns on and starts to boot for a few seconds but before displaying any image it short circuits the main 19V power supply and turns off.

I managed to "repair" the laptop and it turns on and everything works, I even did game tests for the CPU and GPU and everything works but what I did was remove a Mosfet (PQ807) from the VCC_GT power supply.
The VCC_GT power supply has two power lines (PQ807 and PQ809) and I removed the Mosfet from line 1 (PQ807).

I replaced the Mosfet (PQ807) with a new one in good condition but it continues to short circuit, I removed the Mosfet (PQ807) again and it started working again without it.

Is it safe to use the laptop normally without this MOSFET (PQ807) and only work with line 2 of the VCC_GT power supply or will I have future problems?

Thanks

PU805 and PQ807 needs to be replaced together for it to work. The laptop will misbehave under load if PQ807 is removed.

Thanks for your response.

The Laptop also has a dedicated GTX1050 graphics operating, I think that all the graphics load will be directed to the Dedicated GPU and will never need extra power in the CPU graphics, what do you think?

The Portable is for my personal use

iGPU is needed even with machines with dedicated GPU. Recently had an acer nitro gaming laptop with horizontal stripes on display(It had GTX1060). It came after several service attempts where the screen was replaced/Edp cable was replaced and lastly GTX1060 was replaced. You know the solution was to replace SOC.It worked with perfect display after SOC replacement. this proves that igpu is needed even with machines on dedicated GPU. Rest is your choice. manufacturer dont put parts which are not needed-so imho,better to stick with the manufacturers design outlay.
